\015 My 2gb ram stick died, so I decided to upgrade to 4gb instead of just the 3gb from factory. Problem is - it won't boot with 4gb in it. It's the Vista Home Premium x64, and I've read it's 'supposed' to be ok. Is there something I'm doing wrong. (yes, I verified that I'm using the correct type, and that both of the new 2gb sticks work, just won't work together- and even tried a different brand)\015

Most appreciated naturalgal66. Perhaps you would like more information, to put together some of the information I stated in the Clarifications.

This is a motherboard block diagram,

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

This relates to the motherboard model you have. Motherboards used for the Intel Core i7 are of a different design, and technology.

CPU as you know stands for Central Processing Unit, or for short - Processor.

The Processor 'communicates' through the Front Side Bus, (FSB), to the Northbridge chip. (Think of the FSB as a 'Data Highway'. Communication goes back, and forth)

The Northbridge chip handles the Ram Memory, and the high speed graphics card slot. (If used on a particular motherboard) Since it handles a high speed graphics card slot, it only handles PCI-Express or AGP. Not PCI.

The Northbridge chip communicates through the Internal Bus to the Southbridge chip.

The Southbridge chip handles the slower capabilities of the motherboard.Some examples are:1) PCI, and PCIe. (PCIe is PCI Express. It is PCI Express, but relates to the slower PCI Express x1. Not the faster PCI Express x16 used for graphics)

2) Onboard Audio

3) SATA, LAN, and USB ports

4) EthernetAnd other devices.

As you can see the Southbridge chip controls the Onboard graphics, (Integrated graphics) through a PCI bus.It also controls anything that is installed in a PCI slot.

If you have time someday, you may want to look up some of the hardware, and technology used in a personal computer.A lot of information can be found on Wikipedia.You may want to type in Wikipedia's search box,

1) Northbridge (computing)2) Southbridge (computing)3) Front Side Bus4) Sdram, (This page will start you with SDR Sdram. Single Data Rate Sdram. Links are also listed in blue for info on DDR Sdram, DDR2 Sdram, DDR3 Sdram, and includes the new technology coming, DDR4 Sdram)5) Harddrive6) Integrated Drive Electronics, (IDE)7) SATA8) RAID9) Comparison of Nvidia chipsets (Also Comparison of Nvidia graphics processing units10) Comparison of AMD chipsets (Also Comparison of AMD graphics processing units, and also to include Comparison of ATI graphics processing units. 11) GPU12) Clock generator (Did you know that a quartz crystal, is used as an oscillator for a Processor?)

Anything you see in blue is a link to more information about it.

Is it slow? Do you want to upgrade the graphics? Do you have a graphics card installed?

Your motherboard has an LGA775 processor socket. The FSB support will handle processors with up to a 1333MHz FSB.Goes back to that Nvidia nForce 630i chipset.

This is Nvidia.com, and the tech specs of the Nvidia nForce 600 Series Chipsets,

http://www.nvidia.com/page/nforce_600i_t...

You'll see your Nvidia nForce 630i heading on the right side. Notice the Processor support, (CPU)

If you have an Intel Pentium Dual Core E2200 processor, you have a processor with,

1) Two Processor cores on one die chip. That is two processor cores, that operate at a maximum frequency rate of 2200 MHz.Yes, it's like having two processors, because it is two processors.They are on one silicon die chip.

Does Not mean Each processor core operates at the above stated frequency rate.The two processor cores team up on a task.

Crude example:You have one man digging a ditch.Take him out, and replace him with two men.Which scenario get's the job done faster?

2) Operates at a 2200MegaHertz frequency rate, at maximum capacity. (2.2GigaHertz.Mega is approximately 1 Million.Giga is approximately 1 Billion.Hertz stands for Cycles per Second.Your processor can operate up to 2200 Million Cycles per Second)

You can use Intel Core 2 processors. Core2 Duo, and Core2 Quad.

It isn't so much that processors now have dual, or quad processor cores, or the maximum frequency rate that they can operate at.

It is the architecture of the processor, and the - Instruction Sets, that set them apart from older models.

The architecture size has grown smaller, and smaller since your Intel Pentium Dual Core E2200 came out. The Pentium Dual Core was one of the first dual core processors made by Intel.

The E2200 is based on the 65nm architecture. (nm = NanoMeterOne billionth of a meter)Allendale Core. Best Instruction Set is the SSSE3.Has an 800MegaHertz FSB. (800MHZ FSB)1MegaByte of L2 cache.Voltage used is .085 to 1.50 Volts

Economical upgrade recommendation, that would S-M-O-K-E that processor's capabilities, would be an Intel Core2 Duo E7400.

Two processor cores with a maximum frequency rate of 2.8GHz.(2800MHz)Wolfdale Core3MB of L2 cache.45nm architecure1066MHz FSBVoltage used is .085 to 1.3625 VoltsSSE4.1 Instruction Set, (Best implemented Instruction Set used)

(Info about a processors Cache.The processor's Cache is a small memory area for the processor.It is the first memory area the processor addresses. Reasoning is, that the Cache operates at the same frequency rate, as the processor.{Ram Memory is next, followed by the Harddrive. Harddrive is slower because it is a mechanical device}

The more Cache, (L1, L2, and now L3), you have, the faster the processor)

You have a PCI-Express x16 graphics slot. (Expansion slot)It operates on the PCI-Express 1.1 technology.(Goes back to that Nvidia nForce 630i chipset)

NOTE*The PCI Express 2.0 technology, is backward compatible with PCI Express 1.1 technology.You can use a graphics card with the PCI Express 2.0 technology, on a motherboard that has PCI Express 1.1 technology.

You won't get the full capabilities of the graphics card that uses PCI-e 2.0Will you NOTICE? NO

Graphics programs haven't even begun to scratch the bandwidth of PCI-e 1.1, much less PCI-e 2.0So far it is a marketing ploy.

If you do not have a graphics card installed, you could make a world of difference using one. Granted, this would only apply towards graphic intensive programs, applications, or video streaming.Not just surfing the internet.

You could transfer any hardware components you purchased to a newer, better motherboard.

Pliz check ur motherboard that it supports 4gb ram or not. if it supports the 4gb then change the ram or try loading another ram if it starts up then it is ur ram that is making problem.

I upgraded the RAM on Lenovo X200 (745533A) from factory 2GB PC3-8500 to 4GB PC3-8500. Checked the BIOS and recognized the new 4GB memory. The trouble is, after upgrading the RAM, the WIFI stopped working and so with the linked Access Connection! All other softwares are working except the wifi radio. Fn+F5 doesn't worked either. So I tried putting back the factory 2GB, and the Wifi worked back. I purchased the 4GB new and bought the same specs PC3-8500 1066Mhz. So what's wrong?

Possibly the new sticks are defective. Try this: disable the wireless devices before removing the old memory. Install the new memory and reactivate the wireless devices. Another possibility: mislabeled memory. Can you check the new sticks in an ...
